Hey buddies,what's up?!

I'm using an ARM cortex M0 micro called FRDM-KL25Z (what a funky name! I knew that! :) ) . I'd like to run a simple motor at different speed. How can I get different OUTPUT voltages to operate this armature ?

Do I need any extra component which generates altering DC voltages? if so what is it called?

tnx guys

It's a small DC motor(like an Armature). It is supposed to get connected to an ARM micro-controller and automatically change its speed. Actually I'd like to know how I can get altering OUTPUT voltages in this microcontroller. Should I use any special device which generates different voltages or does the ARM micorcontroller in the question "FRDM-KL25Z " have the ability to generate different output voltage?

In fact, if I were to Google "DC motor control microcontroller", I could list several methods for you. As a hint, read up on Pulse Width Modulation or PWM.
